DBIER.

Application led August 1, 1923. Serial No. 655,015.

To all whom t may col/wem.'

Be itv known that I, JULIUs JUDELsoN, citizen of the United States, residin at 1197 Grand Concourse, in the city of ew York, in the county of Bronx and State of New York, have invented certain new and useful Improvements in Driers, of which the following is a specification.

This invention relates to improvements in driers. More particularly it is directed to a drier of thecharacter described adapted for use in private dwelling houses where the driers ordinarily used have a single drying compartment.

One object thereof is to provide a drier of the character and for the purpose described with an improved and highly eliicient heating apparatus for heating the air in the drying compartment, and so constructed and arranged as to prevent any of the gases vor injurious fumes from the burners from coming into contact with the articles or materials being dried.

A further object is to provide a drying apparatus of the character described which shall be comparatively simple in construction and economical and efficient in operation to a high degree.

Other objects of this invention will in $0 part be obvious and in part hereinafter y pointed out.

Certain features herein shown and de# scribed are shown, described and claimed in my co-pending application Serial No. 654:,- 85 362, filed in the United States Patent Office on the 28th of July, 1923, and accordingly not claimed herein.

With the above exception the invention accordingly consists in the features of con- 0 struction, combinations of elements and arrangement of parts which will be exemplified in the construction hereinafter described and of which the scope of application will be indicated in the following claims.

In the accompanying drawings, in which is shown one of the various possible illustrative embodiments of this invention,

Figure 1 is a view in vertical section through a. drier casing or cabinet, showing my improved heater therein, said heater being mainly in elevation but partly in section, the view being taken on the staggered line 1-1 of Figure 2.

Figure 2 is a sectional plan view correspending to Figure 1.

Figure 3 is a view in transverse section on the line 3-3 of Figure 2.

F1gure 4 is a view in transverse section on the line 4-4 of Figure 1.

Referring in detail to the. drawing,

1 represents the drying cabinet which ma be of any desired suitable construction.

n the bottom of the cabinet I provide feet 5 or other means to support a burner casmg 2, and a substantially horizontal flue 3, the latter having the forward end thereof closed and extending into the burner casing. Perforations 3 are provided in the wall of the iue 3 within the said casing.

The rear or inner end of the fiue 3 communlcates with a pair of flues 4, the latter having their forward ends open and being secured in openin s in the wall of the burner casing and isposed above the iue 3 to either side thereof.

Within the cabinet and preferably at the rea thereof, I provide a relatively wide box 6. commumcating at its central upper portion with a tapering outlet 7, which communicates with a chimney 8. The box 6 is perforated preferably in its front and bottom as shown at 6'.

A pipe 9, preferably of smaller diameter than iiues 3 and 4, is positioned between the iues 4, and at its inlet end projects through the rear wall of the burner casing `2, and thence downwardly to the top of the flue 3 where it is secured to the latter and has open communication therewith.

The rear end of pipe 9 projects upwardly through the central portion of box 6 and terminates in the outlet portion 7; so that the draft through the chimney induces a draft or circulation through the pipe 9.

The forward end of the burner casing is positioned within an opening in a front partition 10, and is of approximately V-shape in plan so as todivide the casing into two burner spaces in each of which a burner 11 is located. These burners are 100 shown as gas burners extending longitudinally withln the casing and having a gas supply pipe 12 with suitable cocks but obvlously any suitable construction of burner or any suitable fuel may be employed, and I do not limit myself to the particularI construction of burner nor to the fuel described.

Above each burner 11, a deHector 14 is provided, preferably of inverted il-shaped cross-section to throw the heat outwardly and also to direct the heat toward the inlet ends of Hues 3.

The deflectors 14 may be supported in any suitable manner. lin the form shown in the drawing they are shown secured to brackets l5 fixed to platforms 16 on which the burners are mounted.

rllhe forward or front wall of the burner casing 2 is provided with perforated doors 17 in proximity to each burner 11, and these doors may be damper-controlled in any approved manner to admit air to the system, as may be desired.

The Hues 4 are disposed above and to opposite sides of the Hue 3 and directly communicate therewith at their inner ends. The union or coupling of the Hues 4 with the flue 3 is in the form of a if-connection 18, and the pipe 9 in order to lie between the Hues 4 and above the Hue 3 passes through this YLconnection 18 as clearly shown in Figure 4, so 'that said pipe is heated to high degree by radiation from the Hues 3 and 4, as well as by direct contact with the heated air.

The operation is as follows The a1r heated in cabinet 2 Hows through the Hues 4, thence through the Y-connection 18 and through Hue 3 back to chamber 2. A portion of this air escapes through pipe 9 and is discharged into the outlet 7 of box 6. rlhe air within the chamber or cabinet becomes heated by radiation from the walls of the burner casing 2, the Hues 3 and 4 and from pipe 9, and is drawn through the perforations of box 6 up the chimney 8. rll`he moisture is thus rapidly evaporated from the articles in the cabinet and the maximum results are obtained from the heat of the burners.

llt will thus be seen that there is provided a device in which the several objects of this invention are achieved and which is Well adapted to meet the conditions of practical use.

As various possible embodiments might be made of the above invention and as various changes might be made in the embodiment above set forth, it is to be understood that all -matter herein set forth or shown in the accompanying drawings is to be interpreted as illustrative and not in a limiting sense.

Having thus described my invention I claim as new and desire to secure by Letters Patent,
